Optionally, the virtual display area 300 can be variable or constant,and the virtual display area 300 is not visible to other people exceptthe user wearing the AR glasses 100, and thus does not exist to otherpeople.

Optionally, referring to FIG. 2, a principle schematic diagram of the ARglasses 100 displaying the target image to the virtual display area 300is shown, wherein X represents the texts displayed in the target image,and a dotted line represents a display boundary for displaying accordingto the display direction and the imaging distance, and the virtualdisplay area 300 is located in front of the AR glasses 100 at this time,and within the view field of a user wearing the AR glasses 100, and theuser can see the texts on the virtual display area 300.

Based on the same invention concept, the embodiment of the presentdisclosure provides the AR glasses 100, referring to FIG. 3, the ARglasses 100 include a camera circuit 110 and a display circuit 120.

The camera circuit 110, for example, is a camera, and is configured foracquiring the real-time image of the current visual field range of theuser wearing the AR glasses 100 in the real environment, and sending thereal-time image to the image processing device 200, so that the imageprocessing device 200 adjusts the image to be displayed based on thereal-time image, takes the adjusted image to be displayed as the targetimage, and determines the display direction and the imaging distanceaccording to the real-time image and the environmental scene imagepre-stored in the image processing device 200, wherein the environmentalscene image includes the area 300 corresponding to the virtual displayarea for displaying the target image. Specifically, the camera circuit110 can take a picture of the real-time environment in which the currentuser is located.

The display circuit 120 is configured for receiving the target image,the display direction, and the imaging distance sent by the imageprocessing device 200, and displaying the target image to the virtualdisplay area 300 according to the display direction and the imagingdistance.

Optionally, the camera circuit 110 and the display circuit 120 may be ormay not be communicatively connected to each other. Both the cameracircuit 110 and the display circuit 120 are communicatively connected tothe image processing device 200.

Optionally, the camera circuit 110 is configured for scanning theenvironmental scene within the preset range in the real environment toform the environmental scene image and sending the environmental sceneimage to the image processing device. The environmental scene within thepreset range needs to include the virtual display area 300 fordisplaying the target image.

Optionally, scanning the environmental scene within the preset range inthe real environment can be scanning the entire environmental scene inthe real world, and the environmental scene can be a three-dimensionalspace image.

In some embodiments, referring to FIG. 3, the AR glasses 100 furtherinclude: a light sensing device 130, wherein the light sensing device130 is communicatively connected to the display circuit 120.

The light sensing device 130 is configured for detecting light changesof the environmental scene in the real environment and for sending thelight changes to the display circuit 120.

The display circuit 120 is also configured for adjusting the lenstransmittance of the AR glasses 100 based on the light changes.

Optionally, the display circuit 120 decreases the lens transmittance ofthe AR glasses 100 when the light becomes strong, and increases the lenstransmittance of the AR glasses 100 when the light becomes weak. The ARglasses 100 of the embodiments of the present disclosure allow the userwearing the AR glasses 100 to see the target image more clearly byadjusting the lens transmittance.

Optionally, the AR glasses 100 further include a selection button forselecting a display mode, and options of the selection button include aprojection mode and a spatial mode. The user can select to use theprojection mode or the spatial mode according to the situation of theenvironment scene. Specifically, the display direction of the projectionmode correspondingly changes as the current view field changes and thedisplay direction of the spatial mode is a preset fixed direction.

For example, when the AR glasses 100 use the projection mode, the targetimage including the prompt text always appears in the view field of theAR glasses 100, is displayed in front of the user's eyes, and movesfollowing the changes of the user's head posture.

For another example, when the AR glasses 100 use the spatial mode, theAR glasses 100 scan the environmental scene in the preset range inadvance, and then fix the reminding content as the virtual object at thecertain specific position in space, wherein the certain specificposition is the position of the virtual display area 300 correspondinglydetermined according to the designed display direction and the imagingdistance; and when the head posture changes, a person's sight line canleave the reminding content of the target image.

The AR glasses 100 of the embodiments of the present disclosure canselect different display modes according to different use scenarios, andthe two modes can be easily switched, thereby giving the user a betterexperience in different application scenarios.

Compared with the teleprompter in the related art, the teleprompterusing the AR glasses 100 of the embodiments of the present disclosurepresents the target image display including the words directly in frontof the user, the user can move freely, and the target image can alwaysbe in front of the user's eyes to remind the user of words; or thetarget image is fixed at the specific direction, and when the user needsto watch the words, the words can be seen by user turning the head tothe specific direction, which is convenient to use.

Meanwhile, in the embodiments of the present disclosure, theteleprompter using the AR glasses 100 uses a split-type design toseparate the AR glasses 100 from the image processing device 200, i.e.,the hardware for processing and the hardware for displaying areseparated from each other, that is, the image processing and theformation of the target image are both implemented by the imageprocessing device 200 and sent back to the AR glasses 100 fordisplaying, so as to reduce the weight of the glasses to be easily wornby the user.

Embodiments of the present disclosure can select the different displaymodes according to the different environmental scenarios.

For example, for being used in a lecture in an exhibition hall, thetexts preferably always move along with the speaker (i.e. the user), andthe projection mode of the AR glasses 100 can be used to ensure that thepicture is always in front of the human eyes. Since the current viewfield of the AR glasses 100 is constantly changing, the target image ofthe AR glasses 100 can also constantly adjust the position of thevirtual display area according to the user's view field.

For example, in a lecture in an auditorium, the spatial mode of the ARglasses 100 can be used because the surrounding environmental scene isfixed. Taking the reminding content of the AR glasses 100 as a part ofthe space, like a blackboard or a poster, the virtual display area isfixed at a specific position in the space, and the display style of thetarget image of the AR glasses 100 changes when the environment aroundthe virtual display area changes.

In step S602, whether the display difference between the color of thetext in the image to be displayed and the color of the real-time imageis less than the preset value is determined; if it is, step S603 isperformed, and if it is not, the process ends.

Optionally, before the step S602, color analysis is performed on thereal-time image to obtain the color of the real-time image.

Optionally, the display difference between the color of the texts in theimage to be displayed and the color of the real-time image is greaterthan the preset value, so as to ensure that the color of the texts inthe target image is different from or not similar to the color of thearea corresponding to the real-time image of the current visual fieldrange of the AR glasses 100, so as to facilitate the user to see thecontent displayed in the target image.

In step S603, the color of the text in the image to be displayed isadjusted so that the display difference between the color of the text inthe image to be displayed and the color of the real-time image is notless than a preset value, and then step S608 is executed.

In step S604, it is determined whether or not there is the image of theperson in the real-time image, and if it is, step S605 is executed, andif it is not, the process ends.

In step S605, the display style of the texts in the image to bedisplayed is adjusted so as to separate the texts in the image to bedisplayed from the image of the person; and the display style includesat least one of the following: the display area, the display size, andthe display quantity, then step S608 is executed.

Optionally, the image of the person includes at least part of a body ofthe person, such as a head or a limb. The inventor of the presentdisclosure considers that when there is the image of the person in thereal-time image, the image of the person at least partially coincideswith the texts in the target image, the display effect of the texts inthe target image are affected, and therefore it is necessary to adjustthe display style of the texts in the image to be displayed, so that thetexts in the image to be displayed are separated from the image of theperson, thereby separating the texts in the target image of the virtualdisplay area 300 from the person in the environmental scene in realtime.

Specifically, when the display mode is the spatial mode,the appropriate preset fixed direction and imaging distance are selectedaccording to the pre-stored environmental scene image, thereby selectingthe appropriate virtual display area 300.

In step S610, whether the fixed blocking object image exists in thereal-time image or not is determined, if so, step S611 is executed, andif not, the process ends.

In step S611, the imaging distance of the text in the image to bedisplayed is adjusted, and the adjusted imaging distance is taken as theimaging distance, so that the texts in the image to be displayed areseparated from the fixed blocking object image, and the process goes tostep S609.
